Milton rapidly intensified to a Category 5 hurricane late Monday morning.
Within hours, Milton strengthened to a Category 2, then a Category 3, then a Category 4 and finally a Category 5.
Milton now ranks as the third-greatest 24-hour wind speed intensification for a hurricane in the Atlantic Basin. (Records are based on data since the satellite era began in the 1960s.)
this goes into it a bit and is a good listen in general. https://overcast.fm/+AAyIOzvst0E
